Mark Laing Hi there In previous postings I have asked about assembly variants and the management of the data associated with them. For this posting I am interested to hear about your feedback on a similar but different topic. This is particularly common in the automotive market but I suspect it occurs anywhere a single PCB design board supports many different variants and these need to be managed dynamically on … Read More

Mark Laing Hi there This week I would like to ask for input on assembly variants. For the context of this post I would like to state that an assembly variant is one where the base bare PCB is common to all assembly variants and that the variation is through the presence and absence of parts including part substitution of functionally different parts. Therefore using an Approved Vendor List (AVL) to substitute … Read More

Mark Laing Hi there I have heard of a couple of cases of PCB designs where a common pad is shared between two separate components. At it’s simplest case, two 0603 components lie end to end but instead of four pads, two for each, there are only three in total. The two pads closest to each other overlap meaning only one is visible on the board. In other words they share a common pad. This scenario is typically … Read More
